The message of the most comprehensive climate change report the United States has ever released is clear: climate change is already impacting Americans, and if nothing is done it will devastate the economy and disrupt millions of lives.

Of course, the latest 1,600-page of the National Climate Assessment won’t be enough to change the minds of hardened climate change deniers — most notably, a billionaire businessman who owns and frequents a resort in the coastal town of Palm Beach. Just a few days after the post-Thanksgiving release of the alarming findings, President Donald Trump’s dismissed the work of his own government, saying: “I don’t believe it.”

But climate scientists and experts say the facts are undeniable, pointing to changes that have long been evident in South Florida — rising tidal levels, sunny day flooding, stronger hurricanes, disappearing corals and longer mosquito seasons.

For South Florida, among the most vulnerable regions in the country, the report also underlines that spiraling effects are going to be a lot more costly and challenging than worrying about wet feet when crossing flooded coastal roads during the annual King Tides.
